Indiana's former health commissioner said it's too early to celebrate even though the state's infant mortality rate fell to its lowest recorded level in 2012.

Dr. William VanNess was health commissioner until he stepped down last month.

VanNess told hundreds of people who gathered Thursday for an infant mortality summit that while Indiana had an infant mortality rate of 6.7 deaths per 1,000 live births in 2012 that drop appears to be an anomaly.
